4.1.1 Physical Interfaces

The "EC320" unit provides a set of external interfaces (serial and parallel) as shown in
These interfaces are generally used to support external or system–internal communications as required
by the EC, OAM and CGI functions.

Front Panel Interfaces
In the following a brief description of the front panel interfaces will be given:
– DBG Interface: the DBG interface is available to support application SW debug activities.
Two DBG interfaces are available:
• The first
port is implemented as a twisted-pair 10/100 Mbit Ethernet; it is accessible from the front
through a standard RJ-45 cable connector.
• The second port is a point-to-point low speed UART-based RS-232 serial channel operating at
up to 38400 bit/sec; it is compatible with the operation of the COM port of a PC. The port is
accessible through a USB mini-B type on front panel.
